SPECIFICATION forming part of Letters Patent No. 436,226, datedSeptember 9, 1890.

Application filed January 31, 1890. Serial No. 338,704. (No model.)

To all whom it may concern:v

Be it known that I, GUSTAV FISOHEB, of Greiz, in the Kingdom of Prussiaand German Empire, have invented new and useful Improvements in Locksfor the Automatic Releasing of Transmitting-Belts, Horse-Traces, and theLike, of which the followin gis a specification, reference being hadtherein to the accompanying drawings.

My invention relates to improvements in looks for the automaticreleasing of transmitting-belts, horse-traces, and the like.

According to my invention I construct the fastener in such a manner thatwhen in use the halves of the fastener can be at once disconnectedshould occasion arise. For example, if inyimproved fastener were used inconnection with harness a runaway horse could be disconnected from thecarriage, or the fastener could be used in other situations Where arapid disconnection of attaching parts would avert danger.

In the annexed drawings, Figure 1 is a top or plan view of my improvedfastener employed to connect the ends A A of a belt or strap. Fig. 2 isalongitudinal sectional View of the fastener at the line 00 00, Fig. 1.Fig. 3 is a plan view at the lineB B, Fig. 2, the covering in top plateI) being removed so as to show the parts. Fig. 4 is a cross-section ofFig. 5 is an inner view of the covering in plate 1).

The fastener is made of a strong sole-plate a and a lightercovering-plate b, which is secured to the sole-plate a by the studs 0 de f, the sole-plate being secured to the end of the belt by four rivets00 0c 00 00. Upon the studs 0 and d, I pivot levers g h, which, when thefastener is secure, occupy the position shown in Fig. 3. At the otherend of the sole-plate a, I hinge a T-plate t to the studs and l.

The free longer ends of the levers g h lie against the head of theT-shaped plate 'i,while the two heels of the levers g h stand atacertaindistance apart. The sides of the head of the T-shaped plate 6 areinclined, as clearly shown in the sectional view, Fig. 4., and the sidesof the levers g h are similarly inclined at the part where they rest incontact with the saidT-shaped lever t, from which it will be clearlyseen that if the T-lever t' were free to turn on its hinges k Z it wouldyield upward to side pressure exerted by the levers gh, and thus becleared out of their way.

The portion of the fastener which is attached to the end Aof the beltconsists of a block a, carrying a projecting plate m, to which there isriveted a downwardly-project ing stud 0,which,when the halves of thefastener are united, stands in front of the heels of the levers g h. Solong as the levers g h are held in the position shown at Fig. 3 the stud0 cannot escape between the heels; but if the T-plate 2' were turnedupon its hinges out of the path of the ends of the levers g h, so as toallow the said ends to come together, the opening between the heelsbecomes sufficiently enlarged to allow the stud 0 to slip through, thuscausing the halvesof the fastener to become disconnected. The meanswhereby I prevent the said T-piecez' from turning on its hinges,and thuskeep the halves of the fastener together, are as follows: Upon the topplate I), I hinge a door p, and on the said door 19, I mount a slidingbar y, attached by pinsw w to the doorp, the said pins occupying slotsto, which permit the lock-plate y to have a to-and-fro movement. Thefront part or nose of the bar y goes beneath acatch 3, projecting fromthe plate I). The pin 10' screws into a stop, which rests upon and holdsdown the hinged T-shaped plate 1'. A spring t at the back of the slidinglock-plate y prevents it from becoming loosened by jarring or slidingback of itself.

Under Working conditions the tendency of the levers g h is to lift theplate 2' and force open the door 1); but so long as the door is keptsecured by the sliding bar y this cannot occur.

The bar y carries a ring-bolt r and ring, and

a line or cord 10 is attached to this ring, so-

that in the case of harness, for example, if the horse should bolt andthere is no way of stopping him, by pulling on the lines attached to therings on the trace-fasteners the bar 3 in each fastener is pulled back,and the strain exercised through the stud 0 on the levers g h forcesthem together and makes them lift the T-plate v and door p and turn ontheir points, so as to enlarge the opening between the heels, thusallowing the stud 0 to escape and dis severing the halves of thefastener.

In the case of a driving-belt the line for ICO disconnecting thefastener could be carried along the back of the belt and supported ineyes.

lhe construction of the fastener might be varied, and it may be made ofany suitable metal. a

What I claim, and desire to secure by Letters Patent; of the UnitedStates, is

The herein-described releasing device, consisting of two members,onehaving aprojecting plate and downwardly-extending stud and the otherhaving two swinging levers to swing together and hold said stud, aswinging plate or piece to normallyhold said levers together, and asliding plate and means to normally hold said swinging plate,substantially as described.

In Witness whereof I have hereunto set my hand in presence of twoWitnesses.

GUSTAV FISCHER.
